Short answer: Case hardening builds a hard, wear-resistant surface on a tough metal core — by diffusing carbon, nitrogen or both into the surface layer. Carburizing, nitriding and carbonitriding are the workhorses, chosen by the depth, distortion and core toughness each part needs.

Picking the Process
Compare Nitriding Vs Carburizing for depth and distortion; tie to Metal Heat Treatment Guide, Annealing Vs Normalizing en Stress Relieving Vs Annealing. Refine structure via Metal Grain Size Guide.
Wear & Machining
A hard case fights Metal Wear Mechanisms Guide but is machined before hardening; plan with Metal Machinability Guide and inspect via Metal Ndt Guide.
QA & Supply
Document the process per Mill Test Certificate Guide and protect stock via How To Prevent Metal Rust. HXSCO supplies case-hardenable grades.
